mainlining shenanigans

Intel Software Defined Silicon (SDSi) is a post manufacturing mechanism for activating additional silicon features. Features are enabled through a license activation process. The SDSi driver provides a per socket, sysfs attribute interface for applications to perform 3 main provisioning functions: 1. Provision an Authentication Key Certificate (AKC), a key written to internal NVRAM that is used to authenticate a capability specific activation payload. 2. Provision a Capability Activation Payload (CAP), a token authenticated using the AKC and applied to the CPU configuration to activate a new feature. 3. Read the SDSi State Certificate, containing the CPU configuration state. The operations perform function specific mailbox commands that forward the requests to SDSi hardware to perform authentication of the payloads and enable the silicon configuration (to be made available after power cycling). The SDSi device itself is enumerated as an auxiliary device from the intel_vsec driver and as such has a build dependency on CONFIG_INTEL_VSEC.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
